While the foods previously stated have been shown to reduce or increase risk of developing cancer, there are also foods that people who have already developed cancer can eat to increase their likelihood of shaking the illness, or to ease the symptoms. Malnutrition and muscle degeneration are very common in people with cancer, these have a harshly negative impact on health and survival. As stated before, there is no diet that has been proven to cure cancer, adequate nutrition is a vital component to keeping the body strong enough to aid traditional cancer treatments, improve quality of life in the individual, minimize unpleasant symptoms and assist in recovery. Most people who have developed cancer are urged by doctors to stick to a healthy, balanced diet that often includes a healthy amount of lean protein, fruits, vegetables and whole grains, as well as one that limits or cuts out any risk factors, such as sugar, caffeine, salt, processed foods and alcohol. A study at the University of Edinburgh in the United Kingdom found that a diet that consists mostly of high-quality calories and proteins may assist in reducing muscle atrophy (“Understanding the mechanisms”). Good sources of protein include fish, beans, nuts, seeds, chicken, eggs, and some dairy products. Some side effects of cancer, and sometimes its treatment, can make it difficult for the individual suffering with the illness to eat. Some of these include nausea, stomach pain, diarrhea, constipation, loss of appetite, taste changes, and trouble swallowing. It’s terrible to think about how hard it is to live with such an affliction. In addition, those diagnosed with cancer should avoid taking too many vitamins, as they can act as antioxidants and can sometimes interfere with chemotherapy when taken in large doses.
